Thawed breastmilk question

How long is breastmilk good for once it's been thawed? I have a frozen stash going and there have been times when we will warm the frozen stuff up and then my daughter doesn't drink it. I assumed it was only good for an hour from what I've read. Can you put it back in the fridge once it's been warmed?

After you warm frozen milk, it is only good for one hour. Thawed milk is good in the fridge for 24 hours! I have had to pour milk out for this reason! Now I just pour about 3 oz in a bottle, warm it and feed him..if he wants more that I just warm up another ounce or two
